NetherKingdoms

This mod adds vanilla+ features by replacing the portal frame and Nether portal with a new system.

In order to go to the Nether, the player needs to find a new type of ore: "Hell Ore", which is common between Y-level -50 and 20, then smelt it in a furnace. (Making a Pure Hell Ingot requires 8 Hell Ores and a lava bucket.)

With 3 Pure Hell Ingots, the player can craft a new pickaxe called the Pure Hell Pickaxe, and with 1 more Pure Hell Ingot, may craft a "Compass to Hell".

Next step is to find the Hell Temple structure (the "Compass to Hell" always points at the nearest temple) and get the Flower of Hell. This flower will bloom in the dark and produce the Hell Blossom, but the player must give it the required items. These items can be found in the Hell Temples and can be mined ONLY with the Pure Hell Pickaxe. If the player does not provide the currently required item, the flower will die.

After the "phase shift", if the player provided the item, the flower will keep developing, and now it will require a new item, but if the player could not feed the flower, it will turn into ashes.

These items can be found at the bottom of the "Crying Obsidian Towers", located all around the Hell Temple, and they have 4 types: green (Gem of something Lurking), orange (Gem of something Hunting), yellow (Watching Fibre), and blue (Freezing Fibre).

The player must gather these items at the correct time, as they will decay if held for too long. This means that after collecting these items, an internal countdown starts, and if it reaches 0, the item disappears. This takes effect in inventories and in the player's hand as well.

After harvesting the Hell Blossom, the player can craft the Demolishing Whispers block, which is the gate to the Nether.

After standing on it, the player will be teleported to the Nether and can continue its journey.

Exploring the Temple is not an easy task, and the player needs to be well prepared. In this Temple, the player may find precious items and materials, but may also find danger. - "These temples are from Hell, mazes where the only exit is death. Four materials, made by the Devils, and the origin of the sins, the Flower of Hell."
